Ihe nature of my invention consists in providing a gate or door with a spring for the purpose ofclosing said gate or doorwhen left open. A

To enable others skilled in the art toma-ke and use my invention, I will proceed to describe its Construction and operation.

I construct my gate or door in the usual forms, and apply thereto all appendages of such gates 0r doors. But in order to close the gate or door when left-open, I place a circular rod of' any usual metal, with one end stationary in the post as shown at letter A in the accompanying. drawing, and the other end through a hole in the gate or door at letter B,`and upon' this circular rodI place a coiled wire spring made of brass, iron, steel, or anything which may orri` a spring, after the same fashion as shown at letter C, thereby causing the gate or door to close when left open.

What I claim as my invention, and desire to secure by Letters Patent, is

The application of the circular'rod, and also the coil of wire used as a circular spring, as set forth in the drawing.
